Adjust subplot param

I am no expert, but I think this is a fairly simple thing to solve that could contribute to the overall enhancement of the plot() function.
Running the commands bellow a figure is produced.

If in said figure the 'adjust subplot param' icon is clicked displaying the 'adjust subplot param' control bars and the figure is closed before the 'adjust subplot param' window, Julia crashes.
I don't think this is particularly urgent or difficult to fix, but since it happen to me, as a way of saying thank you, I thought I should point it out so that the Package becomes even better.

Reproduce the issue using the Julia 0.3.2 commands in the report: load PyPlot, create x0 and y0, plot them, open the “adjust subplot param” controls, and close the figure before that window. Trace the crash through the PyPlot and matplotlib interaction; done means closing the windows in that order no longer crashes Julia and the plotting behavior remains intact.
